This is what a new sealed bearing looks like with the seal out . Notice how much grease is in it from the factory . I'm using a tip from one of the guys on a tech site . He removes the seal and works the swepco 103 grease into the bearing and wipes off the access then pops the seal back in . I'm trying this on our tru-turf roller which tends to go through these bearings fairly fast . One season on them so far and there is still a little drag on them , there not spinning as freely or sound dry .
